The invention relatesv to an improvement in eyeglasses, and particularly toa noseclamp or usetherewith.

z The. object of the present invention' is'the provision of a nose-clamp'arranged for .ready coperation withthe usual glasses and 'comprises a pluralityof bearin -arms carry- 1 ing at their ends the `usual pa s for contact.' with the skinand each independently mountticularly to. the accompanying drawings, in

Referring 4particularly'to the drawings, it

will be noted that my invention is shown for use `1n `laonnection W1th the ordinary rimless eyeglasses, includin lenses 1, lthou h it is to v,be understood that the invention in of lens. f

the lens', said lip being perforated forftherethrough the lens and secure the post thereto.

for a purpose w 'ch later appear.V In alinementwiththe respective enl S of t plater the relatively inner edge thereof is proto the plane ofthe lens, as clearly showniin. Fig. 2. The bridge-piece 8.0i the structure is mate side e ge of the'y plate 3. The cross- Wardlyprojecting lip 10,- corresponding in size an and being designed to engage the 4lens on vthe side o posite to the lip l4, said lip 10-being forme with an o ening to receive the secure ving-pin 5. By t is construction the lens# manner to rovide a secure connection with the lens, it eing understood that the lugs 7 bridge-piece.

Thenose-clamp, which forms the material part ofthe present invention ,-is provided with our practically duplicate parts; two being of the nose-clamp comprises a'clamping-arm- 1'1, formed with a pad-section 12 andwith a screwed or handle portion 13. `At the junc- .tionv the yarm is` enlargedlaterally to kprovidefa plate 14, from the ends 'ofwhich .arms are designed for coperation with one lens-post aggregating in width the distance Aon its inner side to conform to the curvature,V of. the lens and formed with an outwardlyfg; .extending centrally-disposed lip '4, project'g, ing fromthe relatively outer'ved e of ,vthe" plate 3 and designed to overlie and ar'uppn.

The plates 14 'of each respective pair of, clamping* vbetweenthe ears 6 ofthe lens-post, so that applied osition said-,arms are arranged side '.byfside- '.etw'een .the ears 6 and-fare pivotallyj liereto Y a: .fpi'n 16 .passing`v` TheV respectiveends of `the plate 3 are` j fornried with relatively inwardly-projecting ,6'5 ears 6, extendinguin parallel spaced' relation'.

provided at one end with a cross-st1ip9,v designed to seat between the lugs 7 of the re' spectivelensosts and bearagainst'theprOXi'-` 75 Y l piece 94 is centrally provided with an outshape to the lip 4 of the lens-posti l post and bridge-'piece are secured in place in a 8 I;

arranged, for coperation with' each lens-post, v as willlappear in thedrawings. Each part f IOC)A the respective pairs of arms are also projected, so as to terminate 1n alinement in rear of the bridge,` whereby` to embrace the nose above and below ,and in rear of the engaging I 5 point of the bridge. The handle portions 13 of the respective pairs of clamping-arms are also curved in such manner that when assembled they will be slightly divergent relative to the res ective plates 14, their projection from the p, ates ina direction opposite to that of the pad portions disposing the handles beyond and forward of the lens-posts in a position to be conveniently and simultaneously operated in applying the eyeglasses.

The free end of each of the pad portions 12 of the clamping-arms is provided with a laterally-projecting pin 17,- formed with a cen-4 trally-reduced portion 18 to loosely receive a concavo-convex disk 19, on the concave or outer side of which disk is secured the pad proper, as 20. Bypreferenca the pad proper 1s made of chamois or .other material and formed of the desired thickness, being preferably provided with a centrally-disposed opening 21, whereby to produce a desired degree of suction in use. The opening in the disk 19 is preferably slightly greater than the Areduced portion 18 of the pin 17, with which said opening coperates, whereby to permit an independent movement of the ad to provide for the accommodation of) saidpad through irregularities 'of the nose-surface Itis to be noted that the clamping-arm of each pair `connected to the lens-posts is arranged for independent movement,if desired,

and to provide for a suitable clam ing action' of each of said arms Isecui'e a coi -'spring 22 beneath the plate 14 of each arm, said spring being coiled about the pivot-pin 16 and with y its terminals connected, respectively, to the plate 3 of the lens-post and to the plate 14 of the respective clamping-arms. Each arm is thus spring-pressed into clam ing position, and the independent action t us provided for each arm enables the particular arm to perform a clamping action on the nose of the wearer wholly independent of any other arm, as willbe obvious.

In the form shown in Figs. 10 to 14, inclusive, the lens-post 23 comprises spaced plates 24, connected at their inner ends by a faceplate 25 and at their outer ends by lensplates 26, projecting in opposite directions and bent to conform to the curvature of the lens. Each of the plates 26 have edge plates 27 to embracethe respectivesurfaces of the lens, said plates 27 being connected attheir free ends by transversely-arranged pins 28 to engage notches 29, appropriately formed in the edges of the lens. A screw 30 is designed for threaded engagement with:`r one of the lates 24,' being'passed loosely through and headed beyond the other of said plates. By this construction the screw 30 may be operated to draw the plates 24 toward each other, and thereby effectively bind the pins 28 in the lens, securing the parts against accidental dis lacement. The bridge 31 of the modifie lform is preferably constructed integral with' the lens-post, projectingtherefrom in such a .way as to leavethe relatively innerv surface of the face-plates 25 unobstructed.4 The face-plate 25 is provided at the respective upper and lower ends with inwardly-projecting ears 32, between'which are disposed the clamping-arms 33 in pairs, p ivctally securedthrough the medium of a pm 34. The

clamping-arms of the mcdified form are identical in construction with thosel of the preferred form, and therefore a detailed description thereof in this connection is'unnecessary.

As a means for controlling the movement v of the respective clamping-armsof the modified form I provide 'a spring 35 for each clamping-arm, said spring being preferably in leaf form with one plate 25 of the lens-post immediately beyond the pivotal connection of the cooperating clamping-arm, as clearly shown in Fig. 13. The spring 35 extends in alinement with the clamping-arm and bears at its free end upon end secured to the facethe relatively outer surface of said arm, preferably at the point overlying the connection of the pad to said arm'.

The operationand use of the structure is readily apparent from the above description,

taken 1n connection with the drawings, it being obvious that by my invention four independent clamping members are provided in connection with the eyeglass, two bearing above and two below thecontacting-point of the bridge. The glasses are thus secured on the nose of the wearer against possibility of accidental displacement.

In connection with the above-described construction it is to be'particularly noted IIS that each clamping-arm is supported' on the lens-post wholly independent of the other clamping-arms and thatits relative position is determined solely by the spring carried byv said arm, so that each pad will readily accommodate itself to the particular irregularities of the surface on which it fbears, thereby insuring a firm even grip upon the nose and avoiding the irregularities of grip ordinarily incident to those nose-clamps in which the bearing pads are independent- Further-V more, the construction provides for the ready renewal of either of thebearing-arms without y interfering in the slightest degree with any of.`l`

the others,e rendering the repair of this portion of my im rovement a matter of com- .nose-clamp' therefor comprising independently-movable clampingarms,` to engage ea'ch side of the nose and means permitting the independent manual manipulation of said arms.

2. The combination With an eyeglass, of a `nose-clamp therefor comprising independently-movable clamping-arms to engage each side of the nose and carrying nose-padsl at their outer ends, a spring ysecured `to -each arm and to the lens-post of the eyeglass structure, and means rejecting beyond said postand means conneetmg said spring tothe lenspost of the eyeglass structure, said arm being extended beyond the connection of said s ring and post to provide an operating-hane. In testimony whereof I aflix my signaturev in presence of two Witnesses.y
